What Is a Time Series Database?

A time series database (TSDB) is a database that is optimized for handling time-stamped or time series data, which is data indexed by time. TSDBs are designed to handle large volumes of time series data efficiently and quickly, with features such as compression, indexing, and aggregation. They typically use a columnar storage format that allows for fast querying and analytics of time series data.

Examples of time series databases include InfluxDB, Prometheus, TimescaleDB, and OpenTSDB. These databases are used in a wide range of applications, including Internet of Things, system monitoring, and financial data analysis.
